My little boy hasn`t seen his father since he was 8 weeks old, we split when i was pregnant and he is now nearly 18mths old. His father, i assume does not want contact, my son didn`t even get a christmas card from his father, and for his birthday his father signed his card with his name, instead of dad/daddy. We haven`t heard from him since. I agree that if your daughters father doesn`t want to know, then you should let it be. As it has been said, a forced relationship may be worse than none at all. I am sure your little girl has enough love around her to fell safe and secure and to grow into a happy healthy child. Good luck in whatever you decide.
